Potential fix for https://github.com/flatcar/update_engine/security/code-scanning/3
To fix the issue, we need to avoid unsigned subtraction in the loop condition. Instead of
count - bytes_written > 0
, we can directly comparebytes_written
withcount
usingbytes_written < count
. This approach avoids the risk of underflow and achieves the same logical result.The fix involves replacing the condition on line 21 with
bytes_written < count
. This change ensures that the loop behaves correctly regardless of the values ofcount
andbytes_written
